It would be a mistake to think that professors and faculty at A&M may not have time to speak and guide students because it is a state university with so many students. For example, in sophomore year, two professors told son to stay after class and talked to him in detail about taking graduate level courses with them. One of them also invited him to meet other senior faculty members in the department. They spoke to him at length about internship opportunities and advised him on how to apply to grad school etc and told him to stop by if he had any other questions. The point is, they are very helpful and have the resources to help. If your kid participates in class discussions and does well academically, there are people here to guide.
I should point out that son was not some famous child prodigy that faculty would have targeted him. He was plain old top 25% in HS. His biggest achievements were National Hispanic scholar, National AP Scholar and National Merit Semifinalist. In college he is a member of one club, not an office holder or some national champ etc. In other words, these faculty members approached him for his performance in class (not because he was some well known celebrity status student).
